Cytiva currently manages 23 pending office actions within the Chemistry & Materials technology area. This portfolio is distributed across 18 distinct examiners and 12 distinct art units. The presence of 18 distinct examiners relative to 23 pending office actions indicates that many examiners are handling a limited number of matters for the company. This distribution suggests that prosecution strategies may need to be tailored to a wide variety of individual examiner preferences rather than a centralized approach.
KARA M PEO is identified as the busiest examiner for this portfolio, currently handling 5 pending office actions. This specific examiner manages a notable portion of the total 23 pending actions compared to the other distinct examiners. Because the portfolio spans 12 distinct art units, the legal team must navigate diverse technical standards and procedural nuances across the Chemistry & Materials sector. The concentration of 5 actions with KARA M PEO suggests that outcomes from this single examiner will have a significant impact on the overall success rate of the pending office actions.
Based on the USPTO statutory response window for each pending office action. 8 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 8 of the docket's apps have a known mailing date.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §101 + other | 4 (17%) |
| §103 only | 2 (9%) |
| §112 only | 1 (4%) |
| Double-patenting + other | 3 (13%) |
| Multi-statute (no §101) | 13 (57%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
